Answer:
Number of 50 paise coins = 72
Explanation:
Total money = 20 + 40 = 60
In this question the total money is given so we need to multiply the value of the coins in the ratio.
10 × 0.10 x + 8 × 0.25x + 9 × 0.50x = 60
x + 2x + 4.5x = 60
7.5 x = 60
x = 8
Number of 50 paise coins = 9 × 8 = 72
That's the final answer.
I hope it will help you.
